Feature request: HEAD requests

[julienmonnard]

It seems that currently, according to these types, the AppRoute is currently not supporting HEAD requests.

ts-rest/libs/ts-rest/core/src/lib/dsl.ts

Lines 48 to 66 in 56b955f

	/**
	* A query endpoint. In REST terms, one using GET.
	*/
	export type AppRouteQuery = AppRouteCommon & {
	method: 'GET';
	};
	/**
	* A mutation endpoint. In REST terms, one using POST, PUT,
	* PATCH, or DELETE.
	*/
	export type AppRouteMutation = AppRouteCommon & {
	method: 'POST' | 'DELETE' | 'PUT' | 'PATCH';
	contentType?:
	| 'application/json'
	| 'multipart/form-data'
	| 'application/x-www-form-urlencoded';
	body: ContractAnyType;
	};

They act pretty much like a GET request, but do not provide a body in the response. This can be useful sometimes, when only want to know the status of the request, or something related to the headers, without having to download the whole content of the response.

Is there any way to handle these in this library? I would also make use of the react-query wrapper, I don't know if something is needed here as well, of it inherits it from the core package.
